Fig. 3

Various ventricular arrhythmias induced by programmed electrical stimulation in infarcted rats. a Eight basic stimuli (S0) at cycle lengths of 100 ms and two extra stimuli (S1 and S2) induced monomorphic ventricular tachycardia (VT). b Eight basic stimuli (S0) and two extra stimuli (S1 and S2) induced polymorphic ventricular tachycardia. c Seven basic stimuli (S0) induced ventricular fibrillation (Vf). d The percentage of inducible total ventricular arrhythmias/ stimulation times.* P < 0.05 vs. MI GFP group; **P < 0.01 vs. MI-PBS group; †P > 0.05 vs. MI-CON group. e Inducibility quotient of induced ventricular arrhythmias 5 weeks after infarction. * P < 0.01 vs. MI GFP group; **P < 0.01 vs. MI-PBS group, †P > 0.05 vs. MI-CON group
